BatchĬreates new sequences of messages from those received. Sorts the sequence based on a property value or JSONata expression result. Result accumulated to produce a single message.

The node provides three modes of operation: Automatic attempts to reverse the action of a previous Split node Manual allows finer control on how the sequence should be joined Reduce New in 0.18 - allows a JSONata expression to be run against each message in the sequence and the Turns a sequence of messages into a single message. Object a message is sent for each key/value pair of the object. Array the message is split into either individual array elements, orĪrrays of a fixed-length. (default: ` `), buffer sequence or into fixed lengths. The exact behaviour of the node depends on the type of msg.payload: String/Buffer the message is split using the specified character Turns a single message into a sequence of messages. There are a number of core nodes that can work across message sequences: Split The split node also attaches information that can be used by the join node to Note: the parts array may contain additional meta-data about the sequence. Properties: a unique identifier for the sequence the message's position within the sequence if known, the total number of messages in the sequence That contains information how the message fits in the sequence. Understanding msg.partsĮach message in a sequence has a property called msg.parts. Into a message sequence where each message has a payload corresponding to one Message sequencesĪ message sequence is an ordered series of messages that are related in some way.įor example, the Split node can turn a single message whose payload is an Array, Note that JSONata expressions look a lot like JavaScript, but have some key differences.
